10 and claimed in my copending application,

Serial Number 218,531 filed in the United States Patent Ofiice on orabout September 9th, 1927, and the salient object of this invention isto provide an improvement in the construction of the device described inthe above named application which will cause the needle, when retracted,to move to a position above the point at which it is to be nextinserted.

Another object of the invention is to arrange a device of the foregoingcharacter in such a. manner that the operation thereof will be verysimple in order that a comparative novice may operate the device and pro25 duce a product of uniform quality.

Other objects will appear hereinafter.

The invention consists in the novel combination and arrangement of partsto be hereinafter described and claimed.

The invention will be best understood by reference to the accompanyingdrawing, showing the preferred form of construction and in which;

Fig. 1 is a side elevational view of a pre- 35 ferred form ofconstruction for my invention in which certain parts are shown insection;

Fig. 2 is a sectional view taken on the line 22 on Fig. 1;

Fig. 3 is a sectional detail view taken substantially on the line 3-3 onFig. 1; and

Figs. 4 to 9 inclusive are partially diagrammatic views depicting thevarious steps in the operation of my device.

Carpet needles of the type to which my invention relates include aneedle having an eye therein and a looper adapted to cooperate with theneedle in order to form loops in the rug on the side adapted to bedisposed 5O upwardly. The needle and the looper are carried onstructures which are mounted in juxtaposition to each other for relativereciprocatory movement. The device disclosed herein is constructedsubstantially similar to the device described and claimed in my abovereferred to copending application.

The mechanism comprises aneedle 10. which is formed substantiallyU-shaped and which embodiesa pointed end 11. The needle 10 has an eye 12formed therein adjacent the pointed end 11 and in operation the weftstrand is adapted to be inserted through the warp and then a looper isslid along the needle through the warp and engages the weft strand so asto retain said strand in position through the warp when the needle isretracted.

The needle 10 is secured in any desired manner, as by the rivets 13, tothe needle member 1 1. The looper which is indicated by 5 in the drawingis secured as by the rivets 16 to looper member 17. As has been statedthe needle is formed substantially U-shaped and the looper is adapted tobe so positioned that it will be disposed in said U- shaped needle so asto be reciprocal therein. The members 14 and 17 include the co-extenslveportions 18 and 19. In the portion 18 of the needle member 14 a slot 20is formed and a rivet 21 is mounted in the juxtaposed portion of theportion 19 of the looper member 17. In the portion 19 of the loopermember 17 a slot 22 is formed and a rivet 23 is mounted in thejuxtaposed portion of the portion 18 of the needle member 1st. The slotsand rivets are arranged so as to permit relative reciprocation betweenthe portions 18 and 19.

The portion 18 is extended and bent into substantially S-shaped portion24: and the portion 19 is extended and is bent into asubstantially$-shaped formation 25; The pertions and include tangs 26 and 27. Theopposite ends of the portions 18 and 19 are extended forwardly and thenbent outwardly and rearwardly so as to provide portions 28 and 29 whichare adapted to terminate adjacent the tangs 26 and 27. -landles 30 and3.1 are disposed around the tangs 26 and 27 and the ce-operatingportions 28 and 29. The above described construction is substantiallyfill similar to that of my hereinbeitore referred to eopendingapplication.

I have found that considerable skill is required for proper manipulationof a device as above described since it is diflieult tor a novice toadvance the needle an equal amount prior to ea h insertion. l havetherefore provided a construction which will cause automatic advancingot the needle. By referring to Fig. 1 it ma. be seen that the needle 10is secured to the portion 18 of the needle mem her it and that thesection of portion 18 to which said needle is attached, is offset as inis at dicated at 82 in the drawings. In the offset portion 32, adjacentthe needle arrying end thereof, two outwardl extending lugs 33 and arestruck. It will be by referring to l i that the lugs or humps aredisposed on each side of he needle 10 and also that these humps extendtoward the portion 19. The riv El and are arranged so as to permit acertain amount of lateral play between the members l t and 17. Theretorewhen the needle member 10 is retracted the peak oil the humps 333 and 34engage the point 2-35 on the looper member 1'? and tend to spring saidmembers apart. This action is utilized to cause 1 *ancen'lent of the ne*dle in the following manner.

llv referring to st to 9 inclusive the manner of operating this needlemay be seen. In these views A, B, and C indicate three strands of a warpand it is to be understood that the device is not limited merely to warpstrands and further the advance not l'nnited to a movement or merely onetrand, but by regulating the size of the humps and B l the needle may becaused to ad *ance over any desired n unber of warp strands dependpoi.the coarseness of the warp. V ini the weft st and.

In F g. 4ithe device is illustrated in the first position, the weit V?has been directed through the 0)". l2 and it is to he inulerstood thatthe weft will he extended beyond the are l! a distance to provide anoverhanging portion T which will serve as a retaining portion and whichis adapted to be securely anclmred so as to prev nt withdrawal ot thewelt stra id a liter inc! rtion. ln the lirst operation and prior to t einsertion the loopcr member ll is r ,trai'te as tar as the slots 20 and22 and the ;l and :23 will permit, thus causing; the iueor ll) to beenteuded forwardly. l needle is thin. llli; tween the warp ands ill andll and, t loop L is formed. The next 0 d picted in Fin wherein ins aaeration is that 10 needle in is lowed ti remain in its relativeposition but e leoper member 1T is run iorwardly so as i tl al a bring:the portion 36 thereof into engagemcn with the surfaces of the varp, itbeing uniilersood that th needle member 1% has been 11 J distancesutlicient o e0. iori'ardlv a to bring the oortion 37 thereof intoengagement with the warp. that 's the portion 37 engages th wett t andand clamps it be tween said portion 3i and said warp. ll will beapparent that the looper 15 moves forwardly through the U-shaped portionof the needle and therefore is dispose l so as to retain loop L. It isto be understood ti at the looper la is preferably formed o t aresilient material such as flat spring steel. it is apparent that whenthe looper member 17 moves forwardly the portion 19 thereot rides alongthe humps 83 and l em out inasmuch as the looper and the needle will beheld in juxtaposed position by the warp strands A and 13 said looperwill be liexed as is indicated in llig. 5. The next step in theoperation of the device 's the retracting oi the needle while reta... upthe leoper in the position indicated in Fig. The needle in partiallyremoved position is indicated in F (3 and it will be noted that the warpstrandr and B are still holdii'ig the needle 10 and the looper 15 insubstant' juxtaposed position. lowever. as soon a the needle iswithdrawn from engagement with the warp strand 1 the resiliency ot thelooper 15 will cause said looper to tend to straighten which willobviously move the needle 10 beyond the warp strand B and in the pre entinstance into a position above the space between the warp strands B andC. Thus it will be seen that the needle is advanced an amount equal tothe size oi the humps 3 3 and 34: which will obviousl} be the amountthat the loopcr 15 tends to straighten and therefore move the needh 10.

In Fig. 8 the ne. :t step of l mcration is depicted. It will he seen iht l e needle it) has been inserted between the va p strands e1 ti B andC and it should he noted that the loopcr 15 is still retainedbetvi'eei'i he warp strands A and ll an l is hold n the loop ll.

i. In l ie 9 the next stzp is depicted. Herein it will he seen that theloopcr 15 has been retracted from the loop L and said loop is free. Thenext step in the peration will be substantially similar to Fig. 5 andthe loopor will move into position between the warp strands ll and t andthe above operations will therefore be repeated. 7

The proper manner of using the device ill to grip the handles ill) and231 between the rs oi each hand and to allow the tium to re on theportions 38 and 39 and to rect the index ling aloi iiortions and 29.Obviously advance is iii the direction oi the needle 10 and thereforeoperation will be begun along the cd a ot the warp on the looper side.It is apparent that the humps 3S aad at will cause a uniform advancementpearance a lVhile I p referred o m quality.
